olenoid is constructed by wrapping 52 turns of wire around a cylinder with a cross-sectional area of 8.0 x 10-4 m2. When the solenoid is shortened by squeezing the turns closer together, the inductance increases to 9.30 x 10-5 H. Determine the change in the length of the solenoid.

What is the relationship between the wavelength of a wave and it's energy?

How can you increase the strength of an electromagnet?

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
